MRAM (magnetoresistive random-access memory) is a type of non-volatile random-access memory that uses magnetic changes to store data. MRAM is faster than other forms of non-volatile random-access memory such as flash memory and is more reliable than dynamic random-access memory (DRAM). MRAM also consumes less power than DRAM, meaning it can operate for longer without draining a system's power supplies. It is used in a variety of embedded applications, such as accelerators, digital signal processors, and control systems. The data stored in MRAM is not lost during power outages, making it ideal for critical systems.
